product description
Rd-01 is a radar module developed by Essence Technology. The module supports Wi-Fi & BLE. The radar part is equipped with Silicon Microelectronics' S3KM111L chip, operating in the 24GHzk band, with a modulation bandwidth of up to 1GHz for each frequency. The working principle is to use FMCW frequency modulated continuous waves to detect human targets in a set space, combined with radar signal processing and accurate human body sensing algorithms, to achieve high-sensitivity human presence state sensing, identify human bodies in motion and stationary states, and calculate auxiliary information such as the distance to the target.
The Wi-Fi & BLE part is equipped with the BL602 chip as the core processor and supports Wi-Fi 802.11b/g/n and BLE 5.0 protocols. This product is mainly used in indoor scenes to sense whether there is movement or micro-motion of the human body in the area.
It transmits the detection results in real time through Wi-Fi & BLE and provides a visual configuration tool that can easily configure the sensing distance range, sensing sensitivity in different intervals and unmanned aerial vehicle. Delay time, etc. It supports GPIO and UART output, and also supports Wi-Fi&BLE for wireless configuration of radar parameters, and can be flexibly applied to different smart scenarios and terminal products.
